The Taipan Survey - Cosmology in the Nearby Universe

点击翻译按钮获取中文摘要

This project aims to support the Taipan (Transforming Astronomical Imaging-surveys through Polychromatic Analysis of Nebulae) survey, which is designed to measure redshifts for 500 000 galaxies and peculiar velocities for 50 000 galaxies in the nearby universe. The survey aims to yield the most precise direct measurement of the present-day expansion rate of the universe, the largest maps of the density and velocity fields of local structures, and new and stringent tests of large-scale gravitational physics using galaxy motions, probing Einstein’s theory of gravity and alternatives. It is expected that the Taipan database will add substantial value to research with the SkyMapper telescope and the Australian SKA Pathfinder. The project also aims to demonstrate an innovative Australian robotic technology ('starbugs') that will be used in the next-generation Giant Magellan Telescope.
